There are lots of other kinds of triangles! And Pyret has lots of other functions that make triangles!

triangle :: (size:: Number, style :: String, color :: String) -> Image

right-triangle :: (base::Number, height::Number, style::String, color::String) -> Image

isosceles-triangle :: (leg::Number, angle::Number, style::String, color::String) -> Image

Why do you think triangle only needs one number, while right-triangle and isosceles-triangle need two numbers and triangle-sas needs three?
